One of my Golden Buffs seemed fine one day, and then her beak was crossed the next.....I think she may have got it caught in some fencing or something, because it went back to normal a little bit later in the day.......very strange.
I did read where a chicken that is cross beaked should have a deeper food dish so they can scoop food up easier......
I've got a little chick right now who didn't walk quite right at first, and is slower growing than the rest.....we affectionately have named him Wobbles. Everybody is fully feathered except him--he's half the size and half feathered......we're letting him live as long as nature does....
YAY FOR THE UNDERDOG! LOL
( I guess I'm a softy.) LOL
Good luck to you, whatever you decide.
